Package net.sf.saxon.s9api.streams

This package provides methods to manipulate XDM values using Java 8 streams. It provides an alternative to XPath navigation of XDM trees, avoiding the high parsing cost and poor compile-time diagnostics of XPath expressions, while being a much higher-level interface than DOM-style navigation from node to node.

Class Summary

Class	Description
Predicates	This non-instantiable class provides a number of useful implementations of the Predicate interface, designed for use when navigating streams of XDM items.
Step<T extends XdmItem>	A Step is a function that can be applied to an item to return a stream of items.
Steps	This non-instantiable class provides a number of useful implementations of the Step interface, used to navigate XDM trees, typically as an argument to XdmValue.select(net.sf.saxon.s9api.streams.Step<T>).
XdmCollectors	This class contains a number of static methods that deliver implementations of the Collector interface suitable for use with streams processing XDM nodes and other items.
XdmStream<T extends XdmItem>	XdmStream extends the capabilities of the standard JDK Stream class.

Exception Summary

Exception	Description
XdmCollectors.MultipleItemException	Unchecked exception that occurs when a collector method such as XdmCollectors.asAtomic() or XdmCollectors.asOptionalNode() is called, and the sequence contains more than one item.
